IMPROVEMENT 1N SASH AND BLIND-MACHINE.

I, RANDOLPH D. HOBART, of county of' Broome and State of vented certain Improvements in Sash and Blind-Machines, of whichthe followin f is a specitication.

My invention relates to the combination of a reciprocating chisel and arotatory and vibratory cutter, in such a mannerithat they shall be capable of relishing and pointing windowsash and hlind-rai1s simul taneously, and also of cutting gains in check or lipsash; the 'object of' the invention being' to accomplish the entire operation by means of machinery, thereby obvi'atng the routine'of hand movements required hy the ordinary method, and giving the work a better Binghamton, in thev n'nish.

Figure l in the accompanying drawing is a perspective view of a nmchineembodying my invention.

Figure 2 is aside view of same.

Figure 3 is the vibratory cutter-holder detached.

A is the base of' the frame.

B is the face-plate, which is attached to the main shaft on the t p of the frame, and answers the purpose of the crank connection and balancewheel.

O is the crank-pin.

I), the pitman or connecting-rod.

E is the vertical chisel-shaft, provided with a crosshead,'F, which connects witlr the pitmau by means of the pin Gr.

This cross-head has also a gives motion tothe vibrating end of which is attacheda horizontal or vibratory cutter, J.

This vibratory lever works the frame.

The upper' arm, b, of the lever, is fit-ted to work freely in the slot of the arm H, and is placed out of' line with the chisel-shaft E, which works on a perpendicular line through the center of the frame, consequently, the lateral vibration of the lever I is in proportion to4 the variation of' the arm b from the perpendicular line ofthe shaft E, as shown bythe dotted lines'in g.1.

The throw ot' the vibratory cutter J is determined by the length of the Io'wer arm of the lever I.

This horizontal cutter is made detachable for the slotted arm, H, which on a pin, a., secured to purpose of'removing it while cutting gains, or it may be soarranged, by connecting with a hinge, that it can be turned up out of the way.

K is the vertical chisel in the lower end oi`-the shaft E.

L is the rotatory cutter forA pointing the corners of the tenons, which is also so arranged that it may be moved out of the way during the operation of cutting gains.

The cutterL is driven by a belt from the pulley M, which receives motion from the pulley 1V 1 New York, have iny lever I, to the lower O is the loose pulley.

The speed of the pulley M is designed to be sevenl projection to allow an outward and inward movement,

and secured in position by a screw, c'.

For relishing and pointing sash, the t-enon having been previously cut by the ordinary process, and the machine adjusted by elevating or depressing the table and guide-plate, for thepurpose of gauging the work to the required range withy the cutters, the rail is placed longitudinally upon the table, with the edge of' the tenon to be cut away or relished turned upward'. It is fthen pressed lengthwise to the chisel K, which, commencing at the end ot' the tcnon, cuts across the grain of the wood to the required depth ofthe relish, and, as the chisel rises, the vibrating cutter'Jiiiiishcs the surface to a horizontal li'ne.

When the tenon is cut away nearly to the shoulder the operation of pointing is accomplished by the contact ot' the upper corner of the tenon with the rotary cutter L, the whole being done at a-single operation.

necessary to remove the cutters J and L, as before'described. The sash-rail is then placed upon its side and moved up to the chisel K, when the operation is performed.

The top check is cut with a cope, to fit the moldings on the sash, and the loweror bottomcheck is cut square to fit the glass-rabbet.

What I claim as my invention is 1. lhe combination ofthe vibrating lever I, and cutter J, chisel K, and rotatory cutter L, substantially as and for the purpose herein set forth.

2. The arrangement of the vibrating lever I, and cutter J, chisel K, and rotatory cutter L, frame A, face-plate B, main shaft and pulleys M, N, and O, cra-nkpin C, ptman D, vertical shaft E, provided with crosshead F, connecting-pin G, table P, and guide-plate S, all being constructed substantially as herein described, for the purpose set forth.
